PENCIL SHARPENER.

Application filed. April 21.,

The invention upon which is based the present application for Letters Patent is an. improvement in pencil sharpeners designed for use with pencils formed of spirally wound paper strips surrounding, usually, solt colored leads or crayons. As is well known, these pencils have an outer covering containing a line of indentations and when it is desired to expose more of the lead, this covering is cut, as with a knife, and a spi rally wound strip or ribbon of the paper is stripped off.

Various appliances to facilitate the sharpeningoi pencils of this character have been proposed, but none seem to have gone into general use, presumably because they are not properly adapted nor designed to cut the covering paper and to strip the spiral ribbon and because their use calls for the exercise of more skill than the average users of these pencils generally possess. I have sought to overcome these objections and have designed an extremely simple and easily operated sharpener which closely resembles in appearance the older forms of wooden pencil Sharpeners and which are applied and used in a similar manner. This device is shown in the annexed drawing.

Fig. 1 is perspective view of the improved sharpener shown as applied to a pencil.

Fig. 2 is a similar view of the device detached; and,

Fig. 3 is a cross section of the same on line 3-3 of Fig. 2, surrounding a pencil.

The sharpener is composed of sheet iron or steel having a cylindrical portion 1, and a tapering portion 2. It is slotted from end to end and at its rear or larger end is an ear 3 bent backwardly to afiiord a leverage for the thumb to turn the device when placed over the end of a pencil. There may be two of these ears or lugs instead of one, if so desired.

Between the cylindrical and tapered portions of the device alongside of the ear 3 is 1924. Serial No. 707,804.

a cut-out part 4, and the edge of the tapered portion beyond this cut is turned inwardly or downwardly as shown at 5, the edge of the turned down portion being sharpened to some extent.

In using this device it is placed over the end of the pencil and turned by the pressure of the thumb against the ear or lug 3. The sharpened edge of the turned down portion 5 is limited by the cut-out portion 4t forming a point 6 for cutting the cover of the spirally wound paper ribbon. This pointed edge cuts into and removes a section about as wide as the distance betweenv two adjacentindentations in the cover or as the spiral paper ribbons. By continuing the turning the pointed edge 6 passes under the spirally wound ribbon and strips it off, the sharpener, owing to its shape fitting closely the end of the pencil so that no more than a single ribbon is thus stripped off. The effect of the cutting edge is clearly indicated in Fig. 3.

The use of this device obviates much inconvenience and very geatly simplifies the sharpening of pencils of this kind. Its cost, both as regards material and manufacture, is very small, as it may be stamped out of sheet metal and shaped by bending.

What I claim is A sharpener for paper pencils of the kind described composed of a cylindrical portion and a tapered portion slotted from end to end, and having a cut-out portion between the cylindrical and tapered portions with one edge of the latter adjacent the cut-out portion sharpened and turned inwardly and so spaced with relation to the cylindrical portion and the tapered portion as to form a means for cutting the cover and stripping a single ribbon of the spirally wound paper.

In testimony whereof I hereto aflix my.
